SDA : serial data input pin
SCL : data transfer clock
EXCS : extension chip selection I/O pin
SMODE : serial transfer mode setting input pin
SPOL : RS polarity selection pin when 3 line serial interface is
selected.
Set to “L” after data transfer or during non-access time
SDA data is shifted at the rising edge of SCL
Internal serial/parallel conversion into 8-bit data occurs at the rising
edge of 8
This pin is internally connected to V
This pin is used when the voltage of each input pin is fixed to V
level.
